How and why does a laser show?

Basically, laser show quite different from conventional headlights, such as moving heads, or normal profile spotlight.

Production of "light":
Conventional light sources such as incandescent or discharge lamps, emit light in many different color spectra from the same time (which then results in white light in addition) and in all directions. This produces a uniform brightness around the bulb. To give a direction to the light it is focused into a beam by means of reflectors. This combination is possible to a certain degree, however, is physically limited. 2011 there were in the moving head fixtures (moving heads) a particular progression to highly focused beams (Clay Paky "Sharpy").

Nevertheless, from traditional light sources no beam generated as generated him a Laser: The so-called "coherence", ie the similarity of light in wavelength (ie "color") and direction, makes the laser light to a special visual effect - just by focusing the total light intensity in a thin stream.
At show lasers, the colors are incidentally generated by the use of several different laser sources , usually red-green-blue, sometimes more. The individual colors are then optically superimposed and by the very rapid dimming of each color (device dependent) almost any color nuances can then be generated.

Generating patterns:

In conventional headlights patterns are generated by so-called "gobo". These are "templates" through which the light appears and then using additional lenses, a corresponding image of the template can be generated in a defined distance. Gobos are available as gobos and metal gobos.
lasers at the patterns on the deflection of the laser beam on two fast-moving mirror can be generated. In combination with the switching on and off of the individual laser sources or the dimming of colors, so almost any pattern can be generated. To this end, laser systems are generally controlled by the computer (via the so-called ILDA protocol).

How does a laser show:

Unlike conventional light (with the properties described above) lasers can be used much more focused and achieve much effects.Unlike the live laser operation in which a laser operator systems for live music served (eg in a club ) can be pre-programmed laser shows, usually in synchronization with a piece of music and / or video track. But also the coupling with other DMX-controlled effects such as moving heads or pyrotechnics is often used.

Generally, laser shows today increasingly becoming multimedia experiences: the laser is indeed the central effect element generated the 3D-like effects in space and the viewer involving, but complement the other media's emotional experience.
important for each laser show here is the projection surface: Mostly are graphic elements are projected on a solid surface with beam shows that radiation effects send out towards the viewer, combined. To visualize the rays in space, it is essential that a certain density of particles in the air is to the beam to provide a reflective surface. In the interiors, a Hazer is normally used to (mist generator) in the outer region are fog machines in combination with strong fans or pyrotechnic smoke effects make sense.

Professional laser shows and multimedia shows of all sizes, for example, from Laserworld offered that also manufacture laser show systems in a wide range of services. Different partners in the Laser World group need to take the individual services.
